From the day I put up our Super Mario Trunk or Treat post, I started getting questions about the Piranha Plant DIY and where the heck the graphics were to make the Question Mark Box. Going to be totally honest here, on the difficulty scale, this plant project is about a 6 or a 7, but you can do it!
Mario Brothers Piranha Plant DIY
As I mentioned, this project is a little tough, but it’s mostly because the materials are so big and hard to manage. It’s do-able, but you’ll likely need a second person to help out a bit.
- Large sheet black foam core
- 18×18 in carboard box (or similar–recycle and save one from Amazon!)
- Small hula hoop – dollar store good place to find
- Piranha plant file (download here)
- Pipe insulation
- Green craft paper (buy it here)
- 4 foot rod
- PVC pipe in cement
- Packing tape
You’ll need to bring the Piranha plant poster to a print center that has a wide format color printer. Grab a coupon before you go! The print will be somewhere in the range of 24″ wide to 48″ long. After you print it out, you’ll need to mount the picture to a piece of black foam core and cut it out with a hot knife. I’ve got a tutorial on how to do that here. Different project, same idea! Watch the video.
After you’ve got your plant cut out, tape your rod to the back. I have a 5 gallon bucket I’ve anchored a 1.5 inch piece of PVC pipe into that I use for ALL kinds of projects (Boat sails, projector screens, balloon arches, etc. etc.) The bucket goes in the green sewer pipe we’re about to make and the the rod goes in the PVC pipe. The bucket will keep your plant from blowing away and keep the graphics upright.
A hula hoop?? What the heck?? Really, it makes great bones for a pipe. The Dollar Tree sells smaller size hula-hoops that are perfect in this setup.
Make the pipe: You’re going to slit your 18x18x18in box open so that all four sides lay flat on the ground. One good vertical cut will do it! Cut the flaps off the top, but save them because they’ll make the lip of the pipe.
We “pre-rolled” the cardboard before we tried to shape it around the hula hoop, which made it easier to work with and easier to convince to be round. With a little bit of help from a friend, wrap the cardboard around the hula hoop and tape the hula hoop to the cardboard with good packing tape.
Use your green craft paper to cover the cardboard.
Make the lip of the pipe: Tape your leftover flaps from your box into one long piece. Cover this uber long cardboard rectangle in paper.
To get a bit of a bump out on the lip, we put a piece of piping insulation (buy at Lowe’s, etc.) at the top of our big green tube and hot glued it down. That part will take some patience.
After the insulation is good and stuck, glue the rectangle to the insulation. You might need a hand to get this part done!
From there, put the cement bucket with PVC pipe in the green “pipe” and put the Piranha plant graphic on a stick into the PVC. And you’re done!
How to make a mario brothers question mark box
This is pretty basic! The print out is sized for a 13×19 paper. Yellow craft paper is the quickest and cleanest way to get the solid yellow look–paint isn’t going to work so great here.
- 18x18x18in cardboard box
- Yellow craft paper (buy it here)
- 13×19 white paper
- Question mark graphics (download here)
Print out and cut out the question mark four times. (Or three, no one will see the back of the box when it’s facing the car.) Wrap your cardboard box in yellow craft paper. Use a glue stick to paste the question mark and four rivets to each side of the box. And you’re done!
